Abstract

Design of a compact ultra wide band filter over 3.1 GHz to 10.6 GHz using broadside coupled lines and folded open circuit stubs in microstrip medium has been presented in this paper. Desired broad band operation is achieved using broadside coupling between feed lines and an embedded floating conductor in the ground plane of a microstrip. Folded open circuit stubs have been incorporated to improve the stop band rejection characteristics of the filter. Filter has been analyzed based on circuit models and full wave simulations. Experimental results of the proposed ultra wide band filter have been verified against the results obtained from circuit models and full wave simulations. Results are in close agreement with each other. The filter measures an overall size of 22Ã—10Ã—0.787 mm³.
